That is great that he responded! I'm sure that made your day. At least your H is responding to you.
My H pretty much quit responding after he cussed me out. He did a little but not much. On his B'day a month later, I just sent him an email & said "Happy Birthday", he sent one back & said "Thank You". That was it. We were cordial when he was moving his stuff out of the house but he had his guard up. I haven't heard from his since he left here April 12th, except the alimony check.
I'm so happy that you are getting some response. I'll keep praying for you also. Thank you for your prayers, I know God does answer them.
